EXTREMES FOR PERIOD OF RECORD - The maximum peak flow of 14,800 ft³/s was obtained from the rating curve extended above 2,400 ft³/s on basis of computation of peak flow over dam at gage height 10.28 ft. and contracted-opening measurement of peak flow. The maximum stage of 15.93 ft. was from high-water marks in gage house.
